+# KX-Bridge – Anycubic Kobra X Moonraker Bridge
+
+**Version:** 0.9.1-beta5  
+**Status:** Public Beta – suitable for home users, feedback welcome
+
+KX-Bridge is a Moonraker-compatible HTTP/WebSocket bridge for the **Anycubic Kobra X** 3D printer. It allows you to control the printer through OrcaSlicer and other Moonraker-compatible software — no Klipper, no Raspberry Pi required.
+
+---
+
+## What's supported?
+
+- Printer status (temperature, progress, state)
+- File transfer and print start
+- Print control: pause, resume, cancel
+- Temperature control during an active print
+- Print speed (Silent / Normal / Sport)
+- AMS filament change (load / unload)
+- Light and fan control
+- Web UI with dashboard, temperature cards, axis control, and camera view
+- Settings and self-update directly in the browser (⚙ menu)
+- OrcaSlicer connection (Moonraker protocol)
+
+---
+
+## Requirements
+
+- Anycubic Kobra X on your local network (LAN, no Wi-Fi client isolation)
+- Printer MQTT credentials (→ see [Extracting credentials](#extracting-credentials))
+- Docker **or** Python 3.9+ **or** the pre-built Linux binary
+
+---
+
+## Quick start – Docker (recommended)
+
+```bash
+# 1. Create .env
+cp .env.example .env
+# Fill in your printer data (→ extract_credentials)
+
+# 2. Start the bridge
+docker compose up -d
+
+# 3. In OrcaSlicer: add printer → "Moonraker" → http://BRIDGE-IP:7125
+```
+
+Check logs:
+```bash
+docker compose logs -f
+```
+
+Update:
+```bash
+docker compose pull && docker compose up -d
+```
+
+---
+
+## Quick start – Binary (Linux)
+
+```bash
+chmod +x kx-bridge
+./kx-bridge --printer-ip 192.168.x.x --username userXXXX --password XXXXX \
+            --device-id XXXXX --mode-id 20030
+```
+
+Or place a `.env` file in the same directory — the bridge reads it automatically.
+
+---
+
+## Quick start – Python directly
+
+```bash
+pip install aiohttp
+python kobrax_moonraker_bridge.py --printer-ip 192.168.x.x ...
+# Or fill in .env and start without arguments
+python kobrax_moonraker_bridge.py
+```
+
+---
+
+## Extracting credentials
+
+The MQTT credentials are printer-specific and are generated on first connection with AnycubicSlicerNext. The `extract_credentials` tool reads them from the memory of the running slicer.
+
+**Requirement:** AnycubicSlicerNext must be running and connected to the printer.
+
+### Windows
+
+```
+extract_credentials.exe --write-env
+```
+
+Writes the found credentials directly to `.env`.
+
+### Linux
+
+```bash
+chmod +x extract_credentials
+./extract_credentials --write-env
+```
+
+### Output
+
+```
+[*] Process found: AnycubicSlicerNext.exe (PID 1234)
+[*] 1986 memory segments read (738.8 MB)
+[*] Analyzing ... 100% (739 MB)
+

+  Device-ID     xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx  (hits: 3504)
+  Printer IP    192.168.x.x  (hits: 3036)
+=======================================================
+
+Hint: pass --write-env to save credentials to '.env'.
+```
+
+All credentials are **processed locally only** — nothing is sent to external servers.
+
+---
+
+## Configuration (.env)
+
+```env
+PRINTER_IP=192.168.x.x       # Printer IP address
+MQTT_PORT=9883                # Default, do not change
+MQTT_USERNAME=userXXXXXXXX   # Starts with "user"
+MQTT_PASSWORD=XXXXXXXXXXXXXX  # ~15 characters, mixed case
+DEVICE_ID=xxxxxxxx...         # 32-character hex string
+MODE_ID=20030                 # Kobra X default
+```
+
+---
+
+## OrcaSlicer setup
+
+1. Add printer → **Anycubic Kobra X** (or generic Klipper printer)
+2. Connection type: **Moonraker**
+3. Host: `http://BRIDGE-HOST:7125`
+4. Test connection → should show "Online"
+
+---
+
+## Web UI
+
+The bridge serves a web interface at `http://BRIDGE-HOST:7125`:
+
+| Section | Function |
+|---------|----------|
+| Dashboard | Printer status, progress, temperature overview |
+| Temperatures | Set nozzle and bed temperature directly |
+| Motion | X/Y/Z movement, motor release |
+| Print Speed | Silent / Normal / Sport |
+| Fan / Light | Fan speed and work light |
+| AMS | Load / unload filament |
+| Camera | Live preview (if supported by printer) |
+| ⚙ Settings | MQTT credentials, poll interval, self-update |
+
+### Self-update
+
+The ⚙ menu in the web UI lets you check for new versions and update the bridge in place — no reinstallation needed. After the download the bridge restarts automatically with the new version.
+
+---
+
+## bridge.sh (Linux service manager)
+
+```bash
+./bridge.sh start    # Start bridge in background
+./bridge.sh stop     # Stop bridge
+./bridge.sh restart  # Restart
+./bridge.sh status   # Check status and port
+./bridge.sh log 50   # Show last 50 log lines
+```
+
+---
+
+## Printer states
+
+The bridge translates internal Kobra states into Moonraker-compatible states:
+
+| Kobra state | Meaning |
+|-------------|---------|
+| free | Ready |
+| printing / busy | Printing |
+| pausing / paused | Paused |
+| resuming / resumed | Resuming |
+| stopping / stoped | Stopping |
+| finished | Complete |
+| canceled | Cancelled |
+| failed | Error |
+
+---
+
+## Troubleshooting
+
+**Port 7125 already in use:**
+```bash
+./bridge.sh stop    # or: fuser -k 7125/tcp
+./bridge.sh start
+```
+
+**Invalid credentials / connection refused:**
+- Start AnycubicSlicerNext, connect to the printer, then run `extract_credentials` again
+- If the result looks uncertain: `extract_credentials --verbose` shows all candidates
+- Manually enter the correct candidate in `.env` and restart the bridge
+
+**Temperature changes are ignored:**
+- During an active print, temperature changes are sent via a separate channel — this is normal and the bridge handles it automatically.
+
+**Docker: Permission denied:**
+```bash
+sudo usermod -aG docker $USER
+# Log out and back in
+```
+
+**Docker: .env not found:**
+```bash
+# .env must be in the same directory as docker-compose.yml
+cp .env.example .env && nano .env
+```
+
+---
+
+## Logs
+
+```bash
+# Docker
+docker compose logs -f kx-bridge
+
+# Binary / Python
+tail -f /tmp/bridge.log   # when using bridge.sh
+```
+
+---
+
+## Security notes
+
+- The bridge binds to `0.0.0.0:7125` by default — use on your local network only
+- `.env` contains printer credentials — do not share publicly
+- The credentials are printer-specific and have no access to Anycubic cloud services
